Problems solved by technology

The valve of the air pump is the key structure that affects the performance of the air pump. Most of the commonly used one-way valves are the structure of the valve combined with the spring. Whether it is the valve at the channel or the valve at the piston end, the spring structure is used, and the spring structure is stable when used. Insufficient performance, but also increases the complexity of the structure, affecting the overall volume of the device

Embodiment 1

[0028] Such as figure 1 , 4 , 5, a one-way valve inflation structure of an air pump, the outer structure is a cylindrical hollow air pump housing 1, for the convenience of description, the air pump housing 1 is placed horizontally; the inside of the air pump housing 1 A horizontal pump body base 2 is fixed in the center, and the pump body base 2 is a horizontal cylinder and is fixedly connected to the air pump housing 1 .

[0029] The outside of the pump body base 2 is concave-convex and sawtooth-shaped. The inner center of the pump body base 2 is a horizontal airflow channel 3. The left end of the airflow channel 3 is connected to an external air pipe 4. The right end of the airflow channel 3 is the airflow channel. Push end 31 .

[0030] The second one-way valve 5 is set at the airflow propelling end 31, and simultaneously, the outer side of the airflow propelling end 31 is surrounded with a concave limit groove, the opening of the limit groove is towards the second one-wa...

Abstract

The invention relates to a one-way valve inflation structure for an inflation pump. An airflow channel is formed in a pump body base. A second one-way valve is arranged at the airflow boosting end. Asection of spring is arranged between the second one-way valve and the airflow boosting end. A compressing chamber is arranged at the outer end of the second one-way valve. A piston assembly is arranged at one end, away from a compressing chamber opening, of the compressing chamber and comprises a piston connecting rod and a piston. A first one-way valve is arranged on the end face of the piston.The first one-way valve is arranged to be in a round sheet shape, and two symmetrical protrusions are arranged on the first one-way valve in the manner of vertically extending outwards from the outeredge. The first one-way valve is made of a soft rubber material. According to the one-way valve inflation structure, wear-resisting fluoro-rubber is used for forming an elastic sheet-like pump film, the pump film can generate elastic deformation along with air pressure change, a channel is opened or closed, deformation is little, however, the inflation requirement is met, and due to the tiny deformation, a pump body can operate more stably and efficiently. The sheet-like pump film is integrally formed, production and installation are facilitated, and meanwhile the structure of the piston assembly is simplified.

Description

technical field [0001] The invention relates to an inflation device, in particular to a one-way valve inflation structure of an air pump. Background technique [0002] The air pump is used to inflate car tires, rubber balls, rubber boats, etc. It is driven by a motor to control the opening and closing of valves, so that the gas enters the pump body, and then enters the tires, balls, etc. The valve of the air pump is the key structure that affects the performance of the air pump. Most of the commonly used one-way valves are the structure of the valve combined with the spring. Whether it is the valve at the channel or the valve at the piston end, the spring structure is used, and the spring structure is stable when used. Insufficient performance, but also increases the complexity of the structure, affecting the overall volume of the device. Contents of the invention [0003] The invention mainly aims at the shortcomings of the one-way valve structure of the air pump, and in...
